House Republican leaders on Tuesday announced their legislative response to a mass shooting at a Florida high school that left 17 people dead — a bill to create a federal grant program for schools to implement threat assessment protocols. But Democrats are already calling the measure insufficient.

The House will vote next week on a bill by Florida GOP Rep. John Rutherford, called the STOP School Violence Act, Majority Leader Kevin McCarthy said.

President Donald Trump signaled Monday he would not support legislation to stiffen gun laws after a 26-year-old man killed more than 20 people at a church in Texas on Sunday.

“Mental health is your problem here. This was a very … deranged individual,” the president said during a news conference in Tokyo with Japanese Prime Minister Shinzo Abe. He said the shooter, Devin Patrick Kelley, had “a lot of problems over a long period of time.”

House Republicans accused the Obama administration of “generally making a mockery” of the congressional oversight process, as they fight in a federal appeals court for documents related to a flawed gun-tracking initiative known as Operation Fast and Furious.

The House Oversight and Government Reform Committee, in a brief filed Thursday at the U.S. Court of Appeals for the District of Columbia Circuit, argued that a lower court judge did not fully correct the Justice Department’s “executive abuses” as it responded to a congressional subpoena.

Despite his support for background checks, for many gun owners in Pennsylvania, Republican Sen. Patrick J. Toomey might be "the lesser of two evils" in his race against Democrat Katie McGinty.

Toomey previously had the support of the National Rifle Association in his Senate run in 2010. But after the 2012 shooting at Sandy Hook Elementary School in Newtown, Connecticut, Toomey teamed up with Democratic Sen. Joe Manchin III of West Virginia, another senator who previously had the NRA's support, to push legislation on background checks.
